OS Upgrade¶

This is a list of steps as guidelines for OS upgrades.

• create a temporary group_vars/<new-suite>/system.yml in a git branch:

---
system:
  distribution:
    debian:
      codename: bullseye
    dc:
      codename: bullseye

• (I often choose ELwing first) ansible-playbook --diff -l Elwing -t apt playbooks/common.yml | tee /tmp/dc.log
• apt upgrade
• apt dist-upgrade (check if removed packages are problematic)
  • accept new version of /etc/services and copy-paste content of local services from /etc/services.dpkg-old to avoid having to redeploy all services
  • do not accept new versions for:
    • /etc/smartd.conf
    • /etc/snmp/snmp.conf
    • /etc/oidentd.conf
    • /etc/sudoers
    • /etc/rsyslog.conf
    • /etc/apt-cacher-ng/acng.conf
    • /etc/zabbix/*
    • /etc/logrotate.d/*
  • check the diff manually for other files
